Plot

From exploding stars to asteroid impacts, Known Universe deconstructs some of the biggest explosions in the universe with unforgettable CGI and slow-motion footage.

The strong chemical bonds in the smallest of substances--such as gunpowder--cause the biggest explosions; the more explosive power of natural disasters and cosmic impacts, such as the one that killed the dinosaurs. What if a similar impact by a near-earth object happened today? What are the odds? Can concentrated sunlight deflect an incoming asteroid? The awesome power of our sun; the viability of using a small body of water to power the world's energy needs. Supernovas and gamma ray bursts; the probability that such would affect the earth. No explosion in the universe compares to The Big Bang. Curiously, contrary to gravity slowing or even reversing its expansion, the universe continues its accelerated expansion. This may be explained by dark energy, which has yet to be detected.
